Abstract
There is disclosed a closure device (1) for attachment to the neck (2) of a container (3). The device has inner (4) and outer (5) coaxial parts movable one relative to the other and each has an exit orifice for the flow of fluid therethrough. The flow of fluid is controlled by one part being movable axially relative to the other part. A control device comprising a frusto-conical valve plug (10) on the outer part controls the flow of fluid from the container so that the movable one of the parts is movable between a closed off condition, an open conical pattern condition, and an open jet stream condition of fluid flow. Accordingly, the user of the closure device has a choice of type of fluid flow to be emitted from the container when the container is squeezed. The inner and outer parts are preferably interconnnected by a quick rise cam arrangement to assist quick separation of the parts.
